Implementierung der Suchfunktion für Anfangsbuchstaben im Adressbuch-js-Tutorial-php.cn

Dieses Mal zeige ich Ihnen die Implementierung der Anfangsbuchstaben-Suchfunktion im Adressbuch. Welche Vorsichtsmaßnahmen gibt es für die Implementierung der Anfangsbuchstaben-Suchfunktion im Adressbuch? Hier ist ein praktischer Fall.

Der Hauptcode lautet wie folgt:
